Concept

The Multiport Selector Valve (MSV) is a compact manifold system with eight inlets and two outlets. Multiple wells streams can be connected to a single body and by means of the special designed internal selector is possible to select and divert the fluids from one well to the test line while all the other remain connected to the production header through the common group outlet.

With this configuration up to seven wells can be connected to each MSV, leaving one inlet free for field seal integrity testing and to allow tandem installations of multiple MSV sharing a single test header featuring in line a Multiphase Flow Measurement System o Test Separator.

The MSV is also successfully used in water injection for Enhanced Oil Recovery projects. In this case the common inlet is diverted to multiple injection points allowing, using the test line, to calibrate each injection point volume, one at a time.
